The Ministry of Defence's (MOD) Defence Science and Technology Laboratory (Dstl) will today present a number of research projects to bring to market the science behind the world's most accurate atomic clocks. ...

According to many scientists, quantum computers will have great importance in the future but, despite all efforts, research in this field is still in its infancy. One of the difficulties is understanding what criteria a quantum ...

Scanning tunneling microscopy (STM) is routinely employed by physicists and chemists to capture atomic-scale images of molecules on surfaces. Now, an international team led by Christian Joachim and co-workers ...

(Phys.org)—One of the surprising predictions of quantum mechanics is that uncharged conductors can attract each other over small distances, even in empty space. While the resulting "Casimir force" has been accurately measured ...

(Phys.org) —At low light, cats see better than humans. Electronic detectors do even better, but eventually they too become more prone to errors at very low light. The fundamental probabilistic nature of ...

A simple mechanical model to effectively implement the well-known double-stranded structure and the elasticity of DNA on a nano-meter scale has been developed by Jae-Hyung Jeon and Wokyung Sung of Pohang ...

Quantum simulators recreate the behaviour on a microscopic scale of biological and quantum systems and even of particles moving at the speed of light. The exact knowledge of these systems will lead to applications ranging ...

Due to their nanoscale dimensions and sensitivity to light, quantum dots are being used for a number of bioimaging applications including in vivo imaging of tumor cells, detection of biomolecules, and measurement ...

(Phys.org)—A quantum computer doesn't need to be a single large device but could be built from a network of small parts, new research from the University of Bristol has demonstrated. As a result, building ...

(Phys.org) —The foundation of many, many modern electronic devices – including computers, smart phones, and televisions – is the silicon transistor. However, the shrinking of consumer electronics is ...

(Phys.org) —One of science's biggest puzzles is figuring out how interacting objects behave collectively. Take water, for example. "It's a molecule, but it's also a liquid with specific properties," says ...

Researchers at Tyndall National Institute, Ireland, have produced the first ever atom-by-atom simulation of nanoscale film growth by atomic layer deposition (ALD) – a thin-film technology used in the production ...

One of the recent revelations by Edward Snowden is that the U.S. National Security Agency is currently developing a quantum computer. Physicists aren't surprised by this news; such a computer could crack the encryption that ...

(Phys.org) —Physicists have created a unique combination of computer models, based on the theory of quantum mechanics, and applied them to a previously well characterised protein found in muscle to develop a new picture ...
